And you can find out about the ouch-ouch factor with Steve Mylon when he uncovers the story of cadmium on next week's Chemistry in Its Element. The top-selling anti-depressant Prozac, the cholesterol-lowering drug Lipitor, and the antibacterial Cipro, all have fluorine to thank for their success. The mass of an atom relative to that of carbon-12. Consider the example of fluorine (see Figure below). Isotopes Atoms of the same element with different numbers of neutrons. It is an intensive property, which is mathematically defined as mass divided by volume: Electron affinity of Fluorine is 328 kJ/mol. Because the flip side of fluorine's extreme reactivity is the strength of the bonds it forms with other atoms, notably including carbon. In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion. Fluorine, a chemical element with the symbol F and atomic number 9, is the lightest halogen and exist as a highly toxic diatomic gas with a pale yellow appearance at normal pressure and temperature.Fluorine is the most reactive chemical element with the highest electronegativity value of 3.98 according to the Pauli scale so that it can react with all other elements except helium, neon, and … However, above this concentration it may cause children’s tooth enamel to become mottled.

Atoms of the same element with different numbers of neutrons. An ion has an unequal number of protons and electrons. If an atom had the same properties as fluorine (F), it would probably be located in. It is the 13th most common element in the Earth’s crust. The small size of the fluorine atom makes it possible to pack a relatively large number of fluorine atoms or ions around a given coordination centre (central atom) where it forms many stable complexes—for example, hexafluorosilicate (SiF 6) 2− and hexafluoroaluminate (AlF 6) 3−. The electronegativity of Fluorine is: χ = 3.98. Uncombined elements have an oxidation state of 0.
